You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Suppose you toss a ball in the air. After leaving your hand, it rises and slows down as it rises. Why? Does it slow down because some force runs out as it rises? Is the force of the hand transferred ...

Daniel Bernoulli (1700-1782) was a Swiss mathematician and physicist best known for his work involving fluid dynamics. He began studying fluids because he was interested in studying the pressure and ...

Kurth Primary and Trout Elementary teachers were dodging Easter marshmallows when sixth-graders from Lufkin Middle School’s STEM prep classes came to present science experiments to second-graders ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
